HEATING AND COOKING STOVE.

SPECIFICATION forming part of Letters Patent No. 442,111, dated December 9, 1890.

T at whom it may concern.-

Be it known that we, ANDREW JACKSON D0 and EDWARD SooTT LORIMER, citizens of the United States, residing at Brookings, in thecounty of Brookings and State of South 'Dakota, have invented certain new and useits object the production of a combined heat ing and cooking stove possessed of great heating capacity and general convenience.

\Ve apply our improvements to wood or coal burning stoves of either the surface-burm ing or the magazine type, and in case of the former we contemplate the addition of a removable magazine when needed. \Ve gain an increased heating eifect by conducting the products of combustion through diving-fines into chambers in the base and thence to the smoke-stack, air being brought into other chambers in the base adjacent to the smokepassages and conducted up. through suitable flues to registers in the sides of the stovebody. We may use either straight divingfiues for the smoke or carry the heated'gases around between the double walls of "rear oven. y

In the drawings, Figure 1 is a perspective view of a stove, showingone side and the rear. Fig. 2 is afront elevation, partly broken away and in section, on a larger scale. Fig. 3 is a top plan view of the heating-chambers in the base, the top being partly broken away 'to show the partitions. Fig. 4 is a side elevation,partly in section, of a modified arrangement, showing the ovens.

The bodyA of a stove may be of any suitable construction. It is provided with the usual feeding-door B, fire-pot C, shaking-grate D, and ash-pit E. Under the bottom of the ash-pit is the heating-box F, which constitutes the base of the stove and is several inches deep. The products of combustion leave the combustion-chamber on each side through the ports a. and pass through horizontal flues G, which extend to the rear of the stove-body and communicate with the diving-fines G, which open into the rear ends of the chambers G These are U-shaped in plan, as seen in Fig. 3, the bendlying at the front of the heating-box, and the two adjacent legs of the chambers being side by side, separated only, by a partition f. At their rear ends these adjacent legs of the chambers G communicate with the upright smoke-stack "G which rises between thediring-flues G behind the stove-body. The course of the smoke is indicated by the undulating arrows.

In the upper part of the smoke-stack is an elbow G, communicating directly with the This connection is for use in starting a fire or in mild weather when a moderate heat is required.

Fresh air is admitted to the heating-box combustion-chamber and provided with a r damper, as shown.

through the air-box H, either from the apartment in which the stove is placed or from the outside of the building, entering the box l-l through a central neck h. A horizontal deflecting-plate h',.suspended midway in the box, compels the. air to pass to the sides and ends of the air-box, which is preferably shaped, as shown. Here the air finds access to the upper part of the box and thence passes through ports 7L into the narrow chambers ll, located between the legs of the U- shaped smoke-chambers G2 in the heatingbox. The air here becomes heated by contact with thehot walls ofthe chambers G and flows into'a narrow chamber H at the rear of the heating-box, whence it enters the chambers 113 at the sides of the same. In these latter chambers are one or more horizontal deflectors f, arranged as shown in Fig.

4, whereby the air is compelled to circulate back and forth in rising through the charm her. It finally escapes through a port f in the top of the heating-box into the side flues H located above the heating-box on either side of the stove-body. From the top of these fines the air enters a space H between the wall of the stove-body on the outside and the ash-pit and fire-pot on the inside, as clearly shown in Fig. 2. The warm air here becomes highly heated by contact with the hot fire-pot, 'andflows out in't o"the room Our arrangements for cooking are as follows: On the outside of each smoke-flue G,"

near its rear end, is an enlargement g, in the shape of an inverted half-cone, which affords space for the formation of a circular opening g in the top of the 'flue and enlargement. This opening is for the reception of cooking utensils, which here receive the full force of the s'moke'a'n'd flame escaping from thestovebody. The opening is provided with a swinging or removable lid 9 and may be fitted toreceive reducing-rings when sinall utensils are usedQ We also contemplate using a rear double-walled oven L, supported on brackets Z, or in anysuitable manner. The diving-flues G in this case are provided with elbows g near top and bottom and with a damper'g midway between them. per elbow communicates with a chamber 1, extending between the double wallsof the oven, over' the top, down at the back and at one'end, and under the bottom to the lower elbow, whereby the products of combustion are compelled to passalmostentirely around the oven." hen the oven is not in use, the damper g can be opened and the smoke permitted to pass directly through the divingflues.

In the top plate of the outer wall of the oven are formed holes 12 for additional cooking utensils. \Ve may also make the stovebody tall enough to accommodate an oven M in the upper part of it above the feedingdoor B.

The oven consists of a cylindrical box having handles m attached to its top, whereby it can be let down into the stove or lifted out, the top A of the stove-body beingremovable. The oven rests on lugs or ears or a projectingflange a on the inside of the stove body. It has a door m in one side that registers with a door B in the stove-body, by which access is had to the oven when in use. The

flange a affords a convenient support for a magazine in case it is desired to use one. The oven M being lifted out, the magazine is The up dropped down into the stove, suitable projections on the outside of the magazine resting upon the flange, as indicated in dotted lines.

Instead of removing the entire oven, it may be provided with a removable top and bottom, and the magazine when inserted will rest upon the inwardly projecting flange around the lower edge-of the oven, on which its removable bottom is supported when in place.

Having thus described our invention, what we claim, and desire to secure by Letters Pat- I '1. A stove having a base com-posed of a heating-box containing smoke-chambers and air-passages H H H the latter having the deflectors f, and the side flues H located above the heating-box and delivering air to the spaces H between the fire-pot and the stove-body, substantially as described.

2. A stove having a base composed of "a heating-box containing smoke-chambers and air-passages,and an air-box underneath the heating-box, provided with a horizontal deflecting-plate and communicating with the air-passages in the heating-box, substantially as described.

3. The combination, with the heating-box F, of the air-box I-Lhaving the central neck 72, the horizontal deflector h, and ports h communicating with the air-passages H in the heating-box, substantially as described.

4. The combination, with'a stove, of the heating-box F, having the U-shaped smokechambers G and the air-passages H H H alternating therewith, the air-box H, having a deflector h, the deflectors f in the chamber H the side fiues'Hfland' the registers I, substantially as described.

5. The combination, with a stove-body, of

' the horizontal flues G, the diving-fines G,

provided with elbows g and dampers g, the oven L, having a space Z between its double walls communicating with the diving-fines, a heating-box F, and smoke-stack G substantially as described.

6. The combination, with a stove-body having the internal flange a, of a removable oven .and a removable magazine for fuel, either one of which can be inserted into the stove and rest upon the flange a, substantially asdescribed.

In testimony whereof we affiX our signatures in presence of two witnesses.
